the elevator whenever it is desired to hold v the elevator againstmovement to" manipulate the parts thereof, aswill be readily understood.Y "The elevator 6 is formed'with a reservoir 9 'which is of generalcylindrical shape throughout the greater portion of its length and isadapted-to receive a composition 10 for marking the goods. Thiscomposition is of a plasticnature and may be or" any de-' sired color.It'is of such form that when exposed to the air or to heat, will hardenand have the general appearance and prop erties of celluloid. ll 7 The"lower endof the reservoir 9 is made with a restricted outlet llnormally registering with; an-opening 12in a slide plate 13. 'This plate13 is supported and held in operative position against the lower endofthe elevator by meansot a bottom plate' l l secured to the bottom ofthe reser f v'oir and having a suitable groove "or recess therein; forthe accommodation of the plate- 13- A plunger'15: is mounted in theupper portion of the reservoir 9 and is provided with a stem'16projecting through a remov able cover 17 of the reservoir and a coiledspring 18 is located aroundthe stem between the'cover'l7 and the plunger15 exerting a sufiicient pressure on the composition to eject the samewhen permittedby the plate 13. The cover v17 preferably hasscrewthreaded engagement with'the reservoir 9 as shown at 19, and ismade with spanner receiving notches20 in its outer face.

The elevator 6 is made in itsupper portioniwith a bore 21 andin itslower portion with a bore 22 of appreciably less'diameter than the bore.21 and sa-id bore22 is of the same diameter as the openlng 12 in plate18 and is located in alinement with an opening '23 in the bottom plate141 A plunger 25 is mounted in thelargerjbore 21 andhas a re.-

duced lower end'26 movable in the reduced: bore22, A coiled spring 27 islocated around the reduced end 26 of .plunger'25 and is housed in thebore 21 so asto exert upwarc'l' pressure on the plunger '25 normallyholding saidplunger invelevated'position; A'screwi 28 in the elevator 6projects into a longitudinal groove 29 in 'the plunger 25 to limit thelongitudinal move ment of theilatter and an enlargement 30. is

provided on'the'u'pper end of the plunger 25 The reduced end 26 of theplunger'25 is made with a do ve-tailed recess 31 to receive adove-tailed tenon 32 on a die to. removably connect the die tothe'plunger. This die fits within the reduced bore 22 of the elevator 6and is movable through the openings 12 and 23 to eject the Compositionand force. it into the goods, I g

A platen 34 is located below the plunger and supported by the base 2.This platen 34 preferably has a screw threaded shank 35 screwed into athreaded opening 36 in the base 2 and is made with spanner receivinnotches 37 to receive a spanner wrench an permit its verticaladjustment. screw 38, which is similar in construction to the platen 34,is adjustably located in a screw threaded opening 39 in the base 2 belowa circular enlargement 40 on the bottom plate 14, and a coiled spring 41is located between the plate 14 and the base 2 and is centered by meansof the enlargement 40 and the screw 38. This spring 41 exerts an upwardpressure on the elevator tending to elevate the same and is weaker thanthe spring 27 so that it is compressed before the spring 27 iscompl'essechas will more fully hereinafter ap ear.

bell crank lever 42 has a slot and pin connection 43 with the casing 1and at its angle is connected by a pivot 44 between two arms 45projecting from the elevator 6. The lower end of the lever 42 has a slotand pin connection 46 with the plate 13 and a set screw 47 is projectedthrough the end wall of casing 1 and limits the movement of this leverinone direction, as shown in Fig. 1, which limits the upward movement ofthe elevator. 7

1n the modification shown in Figs. 5 and 6 1 illustrate a bow springbetween the lever 42 and the elevator 6 which operates to raise theelevator and takes the place of the spring 41 in the preferred form. Inthis modification 1 also illustrate a plunger 49 on top of thecomposition 10 which is pressed downwardly by a coiled spring50 engagedby a disk 51 on the lower end of a stem 52. This stem 52 is provided atone edge with a series of ratchet notches 53 which are engaged by aspring finger 54 on the plunger 25 so that. at each operation of theplunger, the stem 52 will be moved downwardly to put the spring 50 undercompression. A frail ratchet spring 55 is mounted in the cover 56 of thereservoir and projects through a slot 57 therein and this spring holdsthe stem 52 against upward movement. The finger 54 is relativelyweak sothat when the spring 50 is under the desired compression, the finger 54will ride over the ratchet notches 53 in both directions and will movethe stem downwardly only after the spring 50 is expanded. The

purpose of this construction is to maintain the spring 50 under asuitable compresslon sufficient to eject the composition 10. When it isdesired to release the stem, the outwardly projecting end of the ratchetspring 55 can be manually moved to one side as will be readilyunderstood.

Referring particularly to Figs. 1 and 2, the operation of my improveddevice is as follows; The material, not shown, to be marked is insertedin the recessed portion 5 and located above the platen 34. A downwardpressure is applied to the plunger 25 and as the spring 41 is weakerthan the spring 27, this spring 41 will first be com pressed allowingthe elevator 6 to move downwardly. As the elevator 6 moves downwardly,the movement of the lever 42 will compel the plate 13 to move forwardlypositioning the opening 12 therein in alinement with the bore 22 and theopening 23. The adjustment of a screw 38 controls downward movement ofelevator 6 and forward movement of plate 13, thereby insuring exactalinement of opening 1.2 with plunger 26. At the same time this plate 13effectually cuts ofi' or closes the lower end of the reservoir 9. Acontinued downward pressure of the plunger 25 will compress the spring27 forcing the die 33 through the opening 23 of bottom plate 14 carryingwith it the composition which had been located in the opening 12 andpressing this composition into the material above the platen 34. Whenpressure on the plunger 25 is released, the springs 41 and 27 willreturn the parts I to normal position.

As above stated, I employ a composition which will harden when exposedto the air or heat and which will impregnate the cloth or other materialand form a monogram or other suitable identification mark to identifythe material, and which will withstand the laundry operation.

When it is desired to refill the reservoir, the bolt 7 is moved into thenotch 8 locking the elevator in its downward movement. The cover 17 andthe plunger 15 can then be removed and the reservoir filled when saidplunger and cover can be replaced and the device is ready for renewedoperation.

When the die 23 is to be changed, the elevator 6 is locked in elevatedposition by means of bolt 7 and the plunger 25 drawn out, after screw 28is withdrawn, when the die can be replaced.

The die is preferably made in three pieces, each containing separatecharacters, so that any monogram can be formed.

Various slight changes might be made in the general form and arrangementof parts described without departing from the invention, and hence I donot limit myself to the precise details set forth, but consider myselfat liberty to make such changes and alterations as fairly fall withinthe spirit and scope of the appended claims.
